June 18, 2014 Tech in Motion: Tech in Motion Boston Springs Forward "Buzz about Energy Harvester's Walking Charger™ also filled the room, so it was clear that once the company can develop one for commercial use, they have at least 200 promised sales."

"Runner-up in the Haverhill Hardware Horizons Challenge was Energy Harvesters which is producing the Walking Charger, a device that allows users to charge the batteries in their mobile electronics devices just by walking. Here, Larry Grumer, Co-founder and CEO of Energy Harvesters LLC demonstrates the technology at the Merrimack Valley Open Innovation Conference."

"A dead battery is a thorn in the side of smart phone users everywhere, but charging could soon become as easy as putting on your shoes. Energy Harvesters has developed something called a walking charger that could revolutionize the way we charge mobile devices."

"Energy Harvesters ... has literally figured out a way to transfer energy from walking to get into a battery. So the motion of walking translates to electricity that will recharge a battery, for like a cell phone. It's a brilliant idea!"

December 26, 2012 Democrat and Chronicle: Interview with Co-founder, CEO & President, Larry Grumer We had key milestones accomplished with limited capital: Before we could even think about approaching investors. We knew from the beginning that we needed a working prototype to prove that our technology works well, that there would be customer validation from the branded footwear companies and that their customers, the end users — including the military — want our innovation and are willing to pay for it.

Footwear brands: Are excited about our innovation. They want to see a footwear-integrated demonstration prototype in order for them to establish development and supply contracts with us. The military has expressed their serious need for a solution for soldier power and the battery weight overburden carried by soldiers.

According to the creators, the Walking Charger has technological and practical superiority in terms of cost, power output, motion and reliability over other energy harvesting methods including dielectric elastomers, embedded electron charges, piezoelectrics and magnetos.

The company has demonstrated component prototypes to validate their technology and are seek funding to produce an advanced demonstrator as an integrated and cost reduced product.
